It is hard to define the notion of content and style in audio style transfer,
and no universal agreement on the definition of content and style has been reached,
even in well-developed visual style transfer.
However, there are some widely accepted principles, e.g.,
the visual style refers mostly to the space-invariant intra-patch statistics, i.e., to the
texture at several spatial scales, and to the distribution of colors a.k.a. the color palette;
the visual content represents the broad structure of the scene, that is,
its semantic and geometric layout[1]}.
For acoustic scenarios, it usually strongly depends on the context.
